Specification of Letters Patent." P t t d N 30', 192g Application filed February 28, 1920. Serial No. 362,145.

To all whom it may concern:

Be it known thatl, LAFE O, ROBERTS, a citizen of the United States, and a resident of Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Shuttle- Clamps, of which the following is a specification. i

My invention is an improvement in shuttle clamps, and has for its object to rovide mechanism of the character specified by means of which a shuttle may be firmly gripped and held. during winding of the thread.

In the drawings:

Figure 1 is a perspective view showing the device in use;

Fig. 2 is a side view;

Fig. 3 is a View at right angles to Fig. 2;

Fig. 4 is a plan view of the clamp.

The present embodiment of the invention is shown in connection with a shuttle 1, and,

the improvement comprises a clamp formed from a strip of sheet metal of suitable weight and resillency.

ward, as shown at 5, at approximately a right angle to the body of the arm.

This strip is bent' into U-shape, to form a body 2 and arms 3 p 1 Thus the device as a whole is U-shaped, consisting of abody and arms, each arm having a transverse groove on its inner face its free end for engaging the edge'of the side of the shuttle.

By grasping the side of the shuttle, as

shown in Figs. 1 and 2, the shuttle may be firmly held during the winding of the thread. T he shuttle will be held in the left hand while the thread will be wound with the right. Referring to Fig. 4, it will be seen that each of the arms 4; is curved 1 slightly inward intermediate its ends, to

fit the fingers and thumb when grasping the same.

I claim: 1

1. A device of the character specified com prising a clamp of substantially U-shape,

consisting of a body and arms extending approximately parallel, each arm having at its 7 free end and on its inner face a transversely extending groove. for engagement by the edgeof a shuttle face, the extremity of the arm being bent laterally inward beyond the groove.

2. A device of the character specified com-
